If you have been on the look out for a project that combines, RGB LED's, a motor, a microcontroller and a ridiculous amount of hot melt glue, then you have certainly come to the right place.
Allow me to introduce the 'One Chip' Spinning RGB POV Display
This project allows you to create (with minimal components) a fantastic customizable display capable of displaying graphics, animations and text. You can scroll your graphics from top to bottom or use it as a scrolling message display, scrolling from right to left.
The project uses just one chip, eight RGB LED's and a handful of other components to paint animations in 'mid-air!' Plus, together with the included graphic conversion software (download link in step 2) you can easily create your own animations because the software creates all the code for you.
So please, read on and enjoy!
Step 1: Get Your Required Parts and Tools.
Before we set out on this venture, you will need both the components and tools.
1x PIC 18f4680 microcontroller
1 x 40 pin IC socket (optional - to house the microcontroller)
8 x Common cathode RGB LED's
24 x 100 ohm resistors (any wattage)
1 x 0.1 uF capacitor (optional)
2 x 100 uF capacitors
1 x 7805 (5 Volt Regulator)
2 x 10k ohm resistors
1 x hall effect sensor / hall effect switch
1 x 5 pin header (to plug in the pickit2 programmer)
1 x small rare earth magnet (to be used with the sensor)
1 x screw in type mains wiring terminator (See last photo - you get these from a hardware store)
1 x 12v motor
1 x motor (any motor that you can destroy for parts - I.E. the graphite brushes)
1 x 12v powersupply (for the motor)
1 x 7.5 volt power supply (for the POV display - can be upto about 18v)
1 x (5.5cm x 5.5cm blank pcb - aka blank copper clad) - this will be used to transfer power to the display
Holt Melt Glue Sticks
Veroboard / experimenters board
Thin enamel wire (see pic)
Standard single core wire (Like they use in network cable)
- Soldering Iron
- Screw Driver
- hot melt glue gun
- Stanley knife
- side cutters
- pickit2 programmer
- desoldering tool (solder sucker or solder braid - just in case!)
- computer running windows
- swordfish basic compiler (this is a free download - it compiles the code for the microcontroller)
- POV Image Converter (Software that I have made, download link is included in the instructable)
Now that you have all of that, let's get into the construction.
